The area of a trapezium is 480 cm2, the distance between two parallel sides is 15 cm and one of the parallel side is 20 cm. The other parallel side is |
| Answer» E this type of questions first we have to write the all given parameters and then we have to write unknown values and then we have to proceed our answer. So,first we will write our given data :Area of trapezium = 480 cm² The distance between TWO parallel sides = 15 cmOne parallel side is 20 cm.Here we NEED to find the other parallel side. So, first ASSUME the other parallel side as x. Then we have to just plug in the known values in given below formula :Area of trapezium = ½ × (Sum of parallel sides) × (distance between two parallel sides) | |
